System failure and poos customer service

Over the weekend I was searching for a gift for a 30th wedding anniversary vow renewal and Netflorist had just the item I was looking for to my excitement only to discover that I could not edit and personalize the item as the photo frame has a number for the anniversary to be added however the drop down only allows you to add a year like 2019 for example instead of 30. So Saturday 22/06/2019 when I tried calling they had already closed for the day and of course they do not have operators on a Sunday so I called in today, 24/06/2019, spoke with Renee and explained the trouble I was having to which she picked up and had escalated and was fixed about 30minutes later which is great except now the delivery date is only 3 days later which leaves me without the gift I wanted. I called back and told Renee about the situation and said that this was their system issue and if I had not called in they would be non the wiser about it yet she was so unsympathetic and just really uninterested and just saying that well the date shown is the only day that they will deliver the item in my area. I was and am truly upset about this because I am not getting a gift that would mean so much to a very deserving couple, but also the fact that the company being at fault is uninterested in assisting me at all. I truly love the items they have and as pricey as they are I never had a problem but this is just disgusting service and I won't use them again as the disappointment I am left with is way more overwhelming than the previous good experiences had.
